Summary

Balloon dilation effectively treats benign ureteral strictures, achieving a 76% success rate. Early intervention is recommended, as factors like stricture cause and duration significantly impact outcomes.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Benign ureteral strictures can cause significant urinary obstruction.
  • Traditional treatments may be invasive or have limited success.

Purpose of the Study:

  • To evaluate the efficacy of balloon dilation for benign ureteral strictures.
  • To identify factors influencing treatment success.

Main Methods:

  • Percutaneous antegrade or retrograde balloon dilation was performed in 33 patients.
  • A 7-10-F stent was placed post-dilation for 4-8 weeks.
  • Follow-up ranged from 1-40 months.

Main Results:

  • Overall success rate was 76%.
  • Higher success rates were observed in primary ureteropelvic junction strictures (86%) and acute strictures (<3 months, 88%).
  • Lower success rates were noted in postsurgical anastomotic strictures (50%).

Conclusions:

  • Balloon dilation is a viable option for benign ureteral strictures.
  • Stricture etiology, length, and duration are key predictors of success.
  • Prompt balloon dilation intervention is advised.
